Severe hypertension and massive proteinuria in a newborn with renal artery stenosis.

摘要

Renal vein thrombosis and the congenital nephrotic syndrome have been associated with nephrotic-range proteinuriaephrotic syndrome and hypertension in the newborn period. We describe a newborn with severe hypertension and proteinuria secondary to unilateral renal artery stenosis. Proteinuria completely disappeared with blood pressure control (with sodium nitroprusside and an angiotensin-converting enzyme inhibitor). Although renin was not measured, we speculate that proteinuria might have been induced by a high renin state, and was controlled by the angiotensin-converting enzyme inhibitor.
